What are fat-dissolving injections?
Fat-dissolving injections (also called injection lipolysis) are non-surgical cosmetic treatments designed to reduce small, stubborn pockets of fat in specific areas of the body.
They are injectable treatments that break down fat cells under the skin. The body then gradually removes these destroyed fat cells through its natural metabolic processes.
The most commonly used compound is deoxycholic acid, a substance naturally found in the body that helps absorb dietary fat.
Common brands / types
-
Kybella (widely used in the U.S.)
-
Aqualyx
-
Belkyra
Areas treated
These injections are best for small, localized fat deposits, such as:
-
Double chin (most common)
-
Jawline and neck
-
Abdomen (small pockets)
-
Thighs
-
Upper arms (“bingo wings”)
-
Love handles
How it works
-
The injection destroys fat cell membranes.
-
Fat cells break down and release stored fat.
-
The body’s lymphatic system removes the debris over weeks.
Once destroyed, fat cells do not return, but remaining fat cells can still grow if weight increases.
Procedure & sessions
-
Each session takes about 20–30 minutes
-
Multiple injections are given in a grid pattern
-
Usually 2–6 sessions needed, spaced 4–6 weeks apart
-
Results appear gradually over 4–12 weeks
Side effects
These typically occur at the injection site and resolve within a few days to weeks:
-
Swelling (very common, especially under the chin)
-
Redness
-
Pain or tenderness
-
Bruising
-
Itching
Who should avoid it?
-
Pregnant or breastfeeding individuals
-
People with infections in the treatment area
-
Those with certain medical conditions (consult a doctor)
Fat-dissolving injections are not a weight-loss solution. They work best for people who are already close to their ideal weight but want to refine specific areas.
